OVERVIEW

With almost 120 years of experience in the production of

montan and specialty waxes, VOELPKER is one of the most

experienced wax producers in Europe. VOELPKER develops and

produces tailor-made wax derivatives whose chemical functio-

nalities and application properties are precisely adapted to the

specific use.

VOELPKER Plastic Series: At the heart of the WARADUR® (the

subject of this brochure) and CEVO® special wax additives from

VOELPKER is their unique multifunctionality. This enables the

simultaneous resolution of different processing problems. It

leads to improved surface quality and filler or pigment dispersi-

on, improved flow properties and the reduction of friction peaks.

WARADUR® montan wax derivatives also enable the production

of particularly high-quality compounds containing recyclate.

INTRODUCTION

WARADUR® montan waxes are used as high performance addi-

tives in the plastics industry, due to their unique properties and

versatility. Montan wax derivatives serve for example as com-

bined external and internal lubricants, dispersing agents and sur-

face improvers in many types of plastics and processing methods

(Table 1). They are therefore particularly valued for technically

challenging tasks in the engineering plastics field where high

demands are placed on functionality, optical appearance and

cycle time reduction. WARADUR® montan waxes in addition

also provide excellent lubricating and mould release properties

for thermosets.

WARADUR® S

is a mixture of straight-chained monocarboxylic acids with a

chain length in the range of mainly C28 – C32 (montanic acids).

WARAMONT CA

consists of Ca salts of montanic acids (calcium montanate).

WARADUR® E

is an ester wax consisting of esters of montanic acids with

ethylene glycol.

WARADUR® GE

is a glycerol ester wax of montanic acids and exhibits a slightly

higher molecular weight than WARADUR® E. Both esters exhibit

chain length in the range of mainly C58 – C66 and provide low

volatility, good thermostability and low migration rates.

WARADUR® GSM and WARADUR® ESM

are innovative hybrid ester waxes consisting of a mixture of long

chain (mainly C28 – 32) wax acids montan esters and fatty acids

esterified with multihydroxyl alcohols. They combine, on a mo-

lecular level, the chemical properties of montan esters and oleo

esters. Both esters combine in an ideal manner the properties of

montan esters (high thermal stability, low volatility, no blooming

out, excellent release/anti sticking) and fatty esters (e.g. impro-

ved mould release in TPU).

WARADUR® OP

is an ester wax consisting of esters of montanic acids with

multihydroxyl alcohols and contains calcium montanate.

WARADUR® OPplus

is also a montan wax based special wax consisting of esters

of montanic acids with multihydroxyl alcohols. In addition,

WARADUR® OPplus contains an increased amount of calcium

montanate and fatty acid salts and esters.

WARADUR® GSA

is a high-molecular complex ester of montanic acids.

» »Case study: WARADUR® OPSuppression of heavy foaming

A compounder of flame retardant PA66 GF 25 was unable to efficiently mould their compound without strong

foaming. The flame retardant additive was partially degraded due to the high shear forces that occured during pro-

cessing and the acid that was produced initiated degradation also of the polyamide.

The use of WARADUR® OP (0.3 %) instead of calcium stearate reduced the shear stress of the melt to such an

extent that foaming did not occur. The compound could be produced without problems while maintaining the

required fire classification V0 (UL94).

Table 3: Overview of physical data and typical applications

PHYSICAL PROPERTIES

As a result of the long, linear carbon chain as their key structural

element, the montan waxes exhibit good thermal stability and

low volatility (Figure 2b).

Other lubricants like amide wax, calcium stearate, underiva-

tised vegetable ester waxes or polyester waxes from polymer

degradation do not provide the equivalent processing and per-

formance characteristics of montan esters. They also show

differing performance in colour stability (Figure 1) and volatili-

ty (Figure 2a). VOELPKER offers a particularly bright quality of

WARADUR® E.

APPLICATION EXAMPLES

Polyamide (PA)

Polyamides are processed in many different modifications lea-

ding sometimes to critical processing properties. Due to the

polymer’s strong tendency to adhere to hot machine parts, ad-

ditives are required to improve their mould release properties

and so reduce the production cycle time. Especially highly filled

compounds normally do not flow easily in the injection moul-

ding tool. This is mainly due to the distribution but also the

orientation of the fillers and may lead subsequently to reduced

mechanical and optical quality of the final product. WARADUR®

E and especially the partially saponified WARADUR® OP im-

prove the flowability of polyamides through internal lubrication.

As a result, both the filler distribution and orientation of fillers

are improved and the shear stress of the melt is reduced during

compounding and injection moulding. The waxes also reduce the

required demoulding force and provide a better external release

effect than for example amide wax. A concentration of around

0.5 % WARADUR® E or OP in unfilled polyamide is typically used.

Standardised spiral flow experiments clearly demonstrate that

WARADUR® E, and especially WARADUR® OP, improve the flow

of the polymer, resulting in an extension of the flow path in the

flow spiral mould2.

Glass fibre reinforced polyamides intended for processing by in-

jection moulding often contain more than 20 – 30 % of glass

fibre. To improve the dispersion of the glass fiber particles,

the flow properties and mould release, the addition of up to

1.0 % WARADUR® E or OP has been proven to be advantageous3.

Furthermore, the use of WARADUR® E or OP markedly improves

the optical properties (surface gloss, no deposits) of polyamide

mouldings due to a finer and more even distribution of pigments

and of fillers and/or uniform orientation of glass fibers.

» »Case study: WARADUR® EGeneration of uniform conductivity

A manufacturer of a 25 % conductive carbon black-filled PP copolymer was unable to produce his compound

without large variations in conductivity properties. WARADUR® E ensured uniform distribution even when

using twin-screw extruders for the production. The use of WARADUR® E allowed in this case the reduction of

the property variation by one order of magnitude.

Our previous study “POSITIVE EFFECTS OF MONTAN WAXES

ON THE MECHANICAL PROPERTIES OF PA 6 GF 30” analysed

the mechanical properties of PA compounds with 0.5 phr of dif-

ferent lubricants. The study demonstrated that use of calciium

stearate caused a deterioration of mechanical properties. In

contrast, with WARADUR® E and WARADUR® OP a significant

improvement of both the tensile modulus (Figure 3) and Char-

py notch impact strength (Figure 4) was identified. These results

suggest that the WARADUR® wax additives promote a better

dispersion of the used glass fibers.

Ca salts of montanic acid in WARAMONT CA – also contained

in WARADUR® OP and WARADUR® OPplus – act as strong flow

promoters. Significantly reduced cycle times can be achieved in

Case study: WARADUR® ECost reduction / Improved performance

A compounder of carbon fiber reinforced polypropylene compounds for the EE industries was able to reduce the

cost of raw materials. When using 0.5 % WARADUR® E in PP with 8 % CF, a 2 orders of magnitude reduction of

the values for resistance [Ω] and specific electrical resistance [Ω mm²/m] was measured. WARADUR® E causes

a very good distribution and alignment of the individual fibers, so that the conductivity is significantly impro-

ved, which manifests itself in a drop in resistance values.

This significantly improved carbon fiber distribution ultimately lead to a reduction in the cost of raw materials,

e.g. up to. 50 % less carbon fiber usage with about the same conductivity.

Polyolefins

Excellent wetting and dispersion of inorganic and organic

fillers

WARADUR® OP powder can be used as a processing aid in

injection moulding of polyolefins. It serves as an excellent

wetting and dispersion agent for inorganic fillers (e.g. talc and

mineral blends). It improves the flow of the melt and the gloss and

surface texture of the mouldings.

Carbon fiber filled polymers are used in many industries, inclu-

ding aerospace, automotive, and electrical & electronics, due to

their low weight, strength, stiffness and conductivity.

In carbon fiber reinforced polypropylene compounds, the dis-

persing effect of montan waxes such as WARADUR® E and

WARADUR® OPplus could be demonstrated: When using 0.5 %

in PP with 8 % CF, a 2 orders of magnitude reduction of the values

for resistance [Ω] and specific electrical resistance [Ω mm²/m]

was measured.

Montan waxes cause a very good distribution and alignment of

the individual fibers, so that the conductivity is significantly im-

proved, which manifests itself in a drop in resistance values.

This significantly improved distribution of the filler/reinforcer ul-

timately leads to a significant reduction in the cost of raw mate-

rials, e.g. max. 50 % less carbon fiber usage with about the same

conductivity.

advantageous.

TPE

TPEs (thermoplastic elastomers) have achieved widespread

usage and popularity in thousands of products, owing to their

durability, softness and colourability, as well as other benefits.

TPUs (thermoplastic polyurethanes, sometimes described as

TPE-U) for example are extensively used in the automotive,

footwear, transportation and sports industries. The combi-

nation of rubber-like properties and good processing features

makes TPUs an important class of materials. The family of TPUs

comprises a wide range of very soft to hard types. Due to their

flexible, rubbery nature, TPUs tend to adhere to hot machine

parts and to cake during processing. For this reason lubrication

and release agents must meet special requirements.

The montanic ester waxes WARADUR® E and WARADUR®

OP are preferably used in TPU, because they reduce the tack

power and exhibit good lubricant properties at low volatility. One

disadvantage of amide waxes, when used in TPU is their tenden-

cy to migrate. This results in the formation of surface deposits

on the final product. In contrast to amide waxes, the tendency

of montan waxes to migrate is negligible.

WARADUR® E or WARADUR® have an excellent mould release

effect in TPU. As a result of their high compatibility they show

no tendency to migration and they have a low volatility, even

at higher temperatures. The usual concentration is 0.5 – 1.0 %.

WARADUR® E and OP also improve the flow properties of TPU.

Also in other thermoplastic elastomers like TPE-O and TPE-V

montan waxes or special blends of montan waxes with other lu-

bricants have been exhibiting positive application results.

12

PVC

The advantages of montan waxes come to light in PVC especially

when there are high demands made on the quality of the end

product.

Superior surfaces, excellent release effects and

reduced melt viscosity

Among other properties, montan waxes function in PVC as

release agents (“external lubrication”). They improve the surface

quality and smoothness and provide the final product with a su-

perior gloss. Montanic esters are used in materials processed by

injection moulding and other processes that require a good melt

flow, as they also reduce the melt viscosity (“internal lubrication”;

Fig. 1). For example, they show their advantageous lubricating

properties in high-speed cable extrusion, especially at the screw tips.

No plate out, better transparency, low volatility

Montan waxes like WARADUR® E are often used as specialty

high-quality release agents. Apart from the release action, in

contrast to other waxes, they tend not to “plate out”, even at

higher dosage. This ensures good removal of finished parts from

the mould and also a high-quality glossy surface (Fig. 2). Additi-

onally, downstream processing steps such as metalising, printing

and bonding are not significantly influenced4.

InternalLubrication effect

WARADUR® GSM is especially used in rigid PVC processing as

an efficient multifunctional lubricant. WARADUR® GSM is an in-

novative chemical hybrid, that combines structure elements of

montan esters and oleo acid esters.

Also WARADUR® GSA combines internal and external lubricati-

on effects in PVC and provides very low volatility, high thermal

stability and low migration tendency.

Thermosets & epoxides

Montan waxes combine internal lubrication with strong release.

Therefore, they are also suitable for the processing of thermosets

like epoxy resins and phenolic resins (Novolacs). Internal lubrica-

tion helps to improve flow properties whilst external lubrication

reduces the adhesion of the moulding compound to hot machine

parts and improves mould release. WARADUR® OP and also the

special wax blend CEVO®-protect O-6211 are well-introduced in

phenolic resins processing.

14

Montan wax – a lubricant that acts internally and externallyin most polymers

With its polar head and its long nonpolar arms, it acts both inside the polymer matrix and on the polymer/metal (tool) interface.

Low volatility / no ‘plate out’

Thanks to its long arms, its unique structure enables the montan wax to adhere so well in the plastic matrix that it only partially migrates to the component surface and does not cause inconvenient ‘plate out’.

Dispersing effect of montan wax

The unique structure of the montan wax with the polar head and long non-polar arms means that it acts like a surfactant in the plastic matrix. Therefore, very polar ingredients are dispersed excellently in non-polar polymers and their distri-bution is maintained. And it works the other wayas well, which leads to better mechanical results or higher cost efficiency for the masterbatch or compound.
